Thank you! That finally worked, although after a few clicks, as the link returned an error for like 15 minutes and the search on the site for the theme also returned 0 results. Still waiting for a solution to that Office problem, pls.
The theme is not available anymore on Microsoft's site. @DigeratiPrime I'm using Xpize to install the theme, but the renaming of royale.msstyles fails to revive the blue in Office2003. Any solutions?
Already tested it in VM. Works with the old silent install switches: %systemdrive%\install\Symantec\sav10.msi /qb RUNLIVEUPDATE=0 REBOOT=REALLYSUPPRESS.
Welcome, then! Your target is the I386 folder in your installation CD. Find it and the winnt.sif file is in it. Once found, edit it with notepad and search for [GuiRunOnce], which should be among the last sections.
